VSCP Works

The main window for the new VSCP Works. You can define the connections over the different supported transports. Note the raw can and raw mqtt which are general CAN and MQTT support.

Double click on the connection to open the session window

The session window have the same content as for the previous version of VSCP Works

  1. The list of incoming events from the selected connection. Can be filtered, etc. Click on a row to get info about the event. When no row is selected event count is displayed. When several rows are selected time difference calculations are shown.
  2. Status info for event. Click on head to get information about bits.
  3. Timing information for the event.
  4. VSCP class and type information for event. Click on class or type to take you to the help page for the class/type.
  5. GUID for event. GUID’s can be named and if they are the name is shown here. Also sensors (sensor index) can be named. Also shown here.
  6. The data content is displayed also in clear text for all events. Measurements have extended information.
  7. The transmit event area. Transmit events can be defined. Automatic periodic events. Load save to disk as for the previous VSCP Works.

And more…

Here a dump of the event count display shown when no row is selected.

And here when multiple rows are selected making it possible to do event timing calculations.

Still a lot do do but on the way. All written in Qt.

This is quite funny actually. Twenty one year after VSCP was born this man is almost perfectly describing VSCP infrastructure and thoughts.

#VSCP project autogenerated files with units

Units for all measurements and conversion between them is now included in the autogenerated databases and in autogenerated JSON and XML files. Also ASCII and UTF8 symbols are included for each measurement unit.

The unit definitions and formats relay on the mustche format with JavaScript (pseudo) code for the conversion. Simple tools can be used in a project handle this. For this the default unit always is defined as

{{val}}

That is the value (which is a floating point value) is always substituted on it’s own by mustache. For the other unit’s for a specific measurement there are mathematical expressions added to convert that unit to the default unit. With this schema all units can be converted to every other defined unit by first converting it to the default unit.

As an example, for temperature measurements this looks like this

  • unit = 0 (default) is Kelvin: {{val}}
  • unit = 1 is Celsius: {{val}} + 273.15
  • unit = 2 is Fahrenheit: ({{val}} – 273.15) * 1.8 + 32.0
  • unit = 3 is undefined.

A helper for event display is <b>render</b> which for the moment is only defined for vscpworks but can have formats defined for other presenter software as well. The definitions for measurement renderings as an example looks like this today

<render> 
    <vscpworks template=" 
       {{lbl-start}}Unit: {{lbl-end}} = {{unitstr}} [{{unit}}]{{newline}} 
       {{lbl-start}}Sensorindex: {{lbl-end}} = {{sensorindex}}{{newline}} 
       {{lbl-start}}Value: {{lbl-end}} = {{val}}{{symbol}}{{newline}} " /> 
</render>

Mustache is also used here for variable substitution. More info is here.

You find the auto generated files here
